Premature Ventricular Contractions from Benign to Seriousness - A Narrative Updating Review

Nitroglycerine-Responsive Ischemic Trigeminal Premature Ventricular Contractions in Stented Myocardial Infarction with Hypertensive Crises and Transient Ischemic Attack

“…PVCs are early depolarization of the myocardium originating in the ventricle [7] caused by an electrical impulse or ectopic rhythm from any part of the ventricles, including the ventricular septum before the sinoatrial impulse has reached the ventricles. PVCs in absent structural heart disease (SHD) are safe once the risk factors excluded [8]. PVCs with SHD is considered a hallmark of sudden cardiac death (SCD) [8].…”

“…PVCs in absent structural heart disease (SHD) are safe once the risk factors excluded [8]. PVCs with SHD is considered a hallmark of sudden cardiac death (SCD) [8]. Cohort studies revealed that PVCs are accompanied by increased IHD events and SCD [9].…”

“…Cohort studies revealed that PVCs are accompanied by increased IHD events and SCD [9]. Because PVCs with established IHD may be viewed as a marker of disease severity or as an endpoint in the natural history of the disease process [8]. The presence of PVCs in patients of IHD is associated with a poor prognosis [8].…”

“…Because PVCs with established IHD may be viewed as a marker of disease severity or as an endpoint in the natural history of the disease process [8]. The presence of PVCs in patients of IHD is associated with a poor prognosis [8]. Hypertensive crises (76% urgencies and 24% emergencies) represented 3% of all the patient visits, but 27% of all medical emergencies [10].…”
